CALGARY, May 14, 2014 /CNW/ - US Oil Sands Inc. ("US Oil Sands" or the "Company") (TSXV: USO), a company focused on oil sands exploration and
production in Utah announced today that its Board of Directors has
approved the Final Investment Decision to proceed with construction of
its PR Spring Project in Utah. The Company also provided an operational
update and filed its unaudited interim financial statements ("Interim Report") for the three month period ended March 31, 2014 ("Q1 2014") along with the management discussion and analysis ("MD&A") of the financial results of US Oil Sands for such period.

A copy of the aforementioned documents may be found for viewing on the
System for Electronic Document Analysis and Retrieval website at www.sedar.com as well as US Oil Sands' website at www.usoilsandsinc.com.

SELECTED QUARTERLY HIGHLIGHTS

The Board of Directors approved the Final Investment Decision to proceed
with construction of an enhanced Phase 1 Project at its PR Spring
location in Utah. Phase 1 is designed to produce approximately 2,000
barrels per day of bitumen with attractive capital costs, operating
expense, and environmental profile.

With the approved enhancements, Phase 1 can now process a broader range
of oil sand ores while improving solvent and water recovery. Design
enhancements will substantially reduce solvent and water losses;

Phase 1, expected to achieve commercial production in the second half of
2015, is estimated to have capital costs of US$60 million;

Kellogg Brown & Root LLC ("KBR") was selected to provide project and
construction management services for the PR Spring Project. Working
jointly with US Oil Sands, KBR will assist in bringing both the
extraction facilities and mine development into commercial production;

Initiated the procurement of long delivery equipment for PR Spring. The
Company has purchased a rotary slurry mixer, one of the largest pieces
of equipment in the project and will be placing orders for other major
equipment over the next four months as the Company targets installation
in early 2015; and

The Company received approval of its U.S. patent application for its
bitumen extraction process, complementing the issuance of the Canadian
patent in 2012. The approval provides a key, strategic advantage for
the Company, as no commercial oil sands mining process has yet been
implemented that can operate with the overall reduced environmental
footprint that US Oil Sands' process provides.

"Our first quarter has been an exceptional period for our Company, as we
transitioned the PR Spring Project from the design stage to the
execution and build stage" said Cameron Todd, CEO of US Oil Sands.
"Included in this transition was our Board of Directors' approval of
major project enhancements that will enable us to cut our water usage
in half, increase our bio-solvent recovery by 50%, and recover
increased amounts of oil from a broader range of oil sands ore. These
improvements bolster our current credentials of possessing the best
environmental performance in the industry while at the same time,
leading in capital efficiency. This, in combination with our recent
receipt of our U.S. patent approval will ensure US Oil Sands is
uniquely positioned to expand its leading technology to other
developments, greatly enhancing value for shareholders."

OPERATIONAL HIGHLIGHTS

During the first quarter of 2014 the Company continued to work with its
engineering consultants and equipment suppliers to optimize engineering
design on Phase 1 of the PR Spring Project. Project construction,
management and consulting contracts have been awarded to KBR, FLSmidth
USA Inc., and Norwest Corporation. Additionally, the Company continued
to work on future mine planning activities with the assistance of its
third party mine engineering consultants.

Subsequent to the end of quarter, and in compliance with National
Instrument 51-101 - Standards of Disclosure for Oil and Gas Activities, the Company released the independent resource evaluation report issued
by Calgary-based Sproule Unconventional Limited ("Sproule") dated April 2, 2014. The evaluation results detail the bitumen
resource assessment of the Company's PR Spring property in Utah as of
February 28, 2014, and incorporate the results of the 184 wells drilled
and cored on the Company's PR Spring Project Area in 2011 and 2012.
Sproule's independent best estimate of discovered resource is 184.3
million barrels.

OUTLOOK

The Company's Board of Directors approved the Final Investment Decision
to proceed with construction of Phase 1 of its PR Spring Project in
Utah. The added design enhancements will allow the Company to obtain
high bitumen recovery from a broader range of oil sand ores
demonstrating the suitability of the process for expansion across the
Company's Utah leases and potentially to Canada and other deposits
worldwide. These design improvements have the added benefits of
increasing solvent and water recovery, reducing overall operating
costs.

The enhanced project has been approved by the Company's Board of
Directors with estimated capital costs of US$60 million.

For the remainder of 2014, the Company will continue to focus on the
final engineering design and procurement of equipment, as it continues
to progress site preparation and construction of the PR Spring Project
Area. The Company anticipates that a significant portion of the
fabrication of the process extraction plant will be completed in 2014,
with the remaining fabrication and final field assembly to occur in
2015 followed by commercial start-up.

Management has also initiated preliminary mine planning and permitting
activities intended for future production areas within the broader PR
Spring Project Area. In addition, US Oil Sands will continue its long
term strategic goal of acquiring the rights to additional resource
lands by assessing relevant growth opportunities existing outside its
immediate area of operation, including those in international
jurisdictions such as Canada and elsewhere.

Discovered bitumen resources or discovered bitumen initially-in-place is
that quantity of bitumen that is estimated, as of a given date, to be
contained in known accumulations on Company lands prior to production.
Best estimate is considered to be the best estimate of the quantity
that will actually be in-place. It is equally likely that the actual
remaining quantities in-place will be greater or less than the best
estimate. There is no certainty that it will be commercially viable to
produce any portion of the resources. Additional information relating
to resource estimates is contained in the Company's Statement of
